Device management portal, system and method

ABSTRACT

A device management system comprises a processor, a data storage device and a network connection. The data storage device stores weighting data associated with at least one ATM. The processor receives performance metric data from the ATM via the network connection and accesses the weighting data from the data storage device. The processor weights a portion of the performance metric data associated with the ATM with respect to a portion of weighting data associated with the ATM, to produce weighted performance data. The weighted performance data is used in estimating the number of customers unserved during a period of downtime of the ATM.

FIELD OF THE INVENTION

The present invention relates to a device management portal, system and method. More particularly, but not exclusively, the invention relates to a device management portal, system and method that manages a distributed network of self-service devices.

BACKGROUND TO THE INVENTION

Typically, in IP networks of managed devices, such as automated teller machines (ATMs), a simple network management protocol (SNMP) agent runs on each device in the network. These SNMP agents collect performance metric data relating to the operation of the managed devices and send alert messages when a device malfunctions.

Typically, the performance metric data collected by an SNMP agent is in a proprietary format. These proprietary data formats require translation by the SNMP agent into an SNMP compatible form for transmission across a communications network to a network management system (NMS). The NMS runs applications that manage and control the managed devices.

In the case of a network of ATMs, each ATM runs an agent, for example an SNMP agent that monitors a number of performance metrics associated with the operation of the ATM including, inter alia, the downtime of each ATM. It will be understood that the term downtime is used herein to refer to time during which the ATM cannot be used for carrying out transactions, either withdrawal or deposit.

Typically, older ATMs, sometimes referred to a “legacy systems”, monitor downtime using system network architecture (SNA) in which the ATM itself keeps a log of their usage, status and how many operations have taken place in a specified time period, for example how many receipts have been printed since the thermal paper roll was last changed?

Such monitoring of the down time of the ATMs gives a measure of the reliability of the ATM network. However, a simple ATM downtime measurement, in terms of hours and/or minutes, does not give a true measure of the business impact of the ATM downtime on a financial institution. For example, a customer who finds an ATM that is down may complete a transaction in branch, thereby incurring the additional cost for the financial institution of the human involvement of a member of staff in the transaction.

Alternatively, the customer may complete their transaction at the ATM of a second financial institution. The completion of the transaction at the second financial institution's ATM may incur a cost to the first financial institution if the transaction was completed by a customer of the first financial institution, as it becomes a “not on us” transaction. Alternatively, the completion of the transaction at the second financial institution's ATM may reduce charges levied by the first financial institution if the transaction was completed by a customer of another financial institution, as a “not on us” transaction is lost by the first financial institution.

Downtime occurring during an ATM's high usage period, for example lunchtime the day following Thanksgiving, has a greater impact upon the number of customers who cannot be serviced, than downtime during a low usage period or at a low usage ATM. However, using time based current metrics downtime at high usage ATMs, or during high usage periods, contributes equally to an overall downtime measurement as downtime occurring at low usage periods, for example two a.m. on Thanksgiving morning. This is despite the great disparity in the numbers of customers that this downtime would affect.

Recurring instances of ATM downtime at high usage periods affects customer satisfaction, and can ultimately reduce customer retention.

Using current metrics it is not possible to schedule maintenance routes based upon the ATMs currently down that have the greatest customer impact.

Currently, there is no integrated environment in which key performance indicators (KPIs) can be monitored and tracked. This results in a lack of coherent planning and scheduling based upon KPIs.

DETAILED DESCRIPTION

Referring now to FIG. 1, a managed network of ATMs 100 comprises ATMs 102 a-d, a communications network 104, an authorization host 106, a management unit 108 and an interchange network 110.

Each ATM 102 a-d comprises a processor 112, other features of the ATMs 102 a-d will be known to those skilled in the art. Each ATM 102 a-d runs a management agent 114 upon their respective processors 112. Typically, the management agent 114 is an SNMP management agent.

The communications network 104 comprises a secure network over which transactions data for transactions executed at the ATMs 102 a-d passes to the authorization host 106. Typically, the communications network 104 is a private network or a VPN.

The authorization host 106 authorizes “on us” transactions (that is, where the financial institution operating the ATM network 100 is also the issuer of a card used by the customer), and can route “not on us” transactions to authorization hosts of other financial institutions via the interchange network 110.

The management unit 108 comprises a data storage device 116, a processor 118 and a network connection 120. The data storage device 116 stores temporal usage data for each of the ATMs 102 a-d in the managed network 100. Typically, the usage data is historical usage data. For example, the usage data may comprise the average daily usage of each ATM over the previous month. Usually, the daily usage is divided into time periods, such as quarter of an hour or half hourly units.

Alternatively, or additionally, the usage data may be projected usage data. The projected usage data may be calculated from theoretical models based upon population density, spending patterns and the location of an ATM 102 a-d. Such projected usage data may be combined with historical usage data to compensate for seasonal trends, or special one off events. For example, in the weeks running up to Christmas an ATM 102 a-d located in a shopping mall would be expected to have significantly increased usage over the average for November. Accordingly, a scaling factor to historical data can be used to compensate for this seasonal variation. Similarly, if a major sporting event, such as the Superbowl, or a rock concert is anticipated by a financial institution scaling factors can be applied to historical data to provide improved accuracy of temporal usage data.

The management agent 114 collects status and performance data about the operation of its respective ATM 102 a-d. For example, the management agent 114 may receive a status message indicating that and ATM 102 a-d is low on banknotes. As another example, the management agent 114 may receive an error message indicating that there is a jam in the receipt printer of an ATM 102 a-d. In a third example, the management agent 114 may receive an error message indicating that there is a failure in a critical component, such as a cash dispenser device. The first of the above two examples represent non-critical events that do not necessitate immediate maintenance, whereas the third example constitutes a critical event requiring immediate maintenance.

The management agent 114 then transmits this status and performance data across the communications network 104 to the management unit 108 via the network connection 120. One element of the status and performance data transmitted to the management unit 108 is the time, and duration of downtime, of each ATM 102 a-d.

The processor 118 accesses the data storage device 116 and reads the temporal usage data for an ATM 102 a-d that has experienced downtime corresponding to the time and duration of the ATM's downtime. The processor 118 weights the downtime with the temporal usage data to provide an estimate of customers who have not been able to fulfill their transaction during the ATM's downtime, an unserved customer (UC) metric.

This UC metric can be used to determine potential lost revenues from ATM downtime. For example, if the ATM suffering the outage is located in a financial institution's own branch the lost revenues may be less than if the ATM is standalone with a competitor's ATM adjacent to it. However, lost revenues will be less if the ATM suffering the outage is one of multiple ATMs operated by the financial institution grouped together as a customer can use another of the grouped ATMs. A flagging of single or grouped ATMs at the NMS improves the accuracy of modeling of lost revenue.

In a further example, an ATM in an airport or tourist attraction may execute a high percentage of credit card transactions, which attract a higher transaction fee than “on us” transactions carried out a neighborhood branch. Thus, the incorporation of a fee compensation factor further improves the accuracy of an estimate of lost revenue associated with ATM downtime. Such a fee compensation factor may be the averaged fee revenue generated by the ATM over a time period, for example one month.

Currently, ATM downtime reflects downtime over twenty four hour period. Whilst this may be appropriate for a 24/7 convenience store or a drive through ATM, it may not be appropriate to an ATM located in a lobby of a financial institution's branch where access is restricted to, for example, nine a.m. to four p.m. Downtime outside of time periods where the ATM is accessible does not impact directly on the business of the financial institution operating the ATM. A usage window that discounts downtime outside of hours where the ATM is accessible can be used to prevent non-impacting downtime being included in UC determination.

Any combination of the above situations can be accounted for in the weighting of the downtime by appropriate user defined weighting factors in order to further improve how accurately the UC KPI models the effect of ATM downtime on a financial institutions business.

It will be appreciated that whilst the above mentioned user defined weighting factors can be applied to the UC KPI the use of user defined weighting factors is optional. Such user defined weighting factors can be defined for a single ATM or a group of ATMs. A grouping of ATMs may be defined by, for example, geographical location, hours of availability, whether the ATM is standalone or grouped, proximity to competitor's ATM or branch.

Once appropriate UC and user defined weightings, if appropriate, have been applied to each ATM 102 a-d in the managed network 100 it is possible to rank the ATMs 102 a-d according to the impact of their downtime on the financial institutions business. Such a ranking allows the scheduling of ATM maintenance on the basis of business impact. This can reduce the downtime of a financial institutions most popular, highest earning or otherwise key ATMs. Such reduced downtime improves customer retention.

Along with ATM downtime a large number of other KPIs are transmitted from the management agent 114 to the management unit 108. Non-limiting examples of such KPIs include ATM availability, cash outs, cash in network, transaction volumes, acceptance or refusal of marketing offers, transaction approval rates, session time per transaction, and incidents causing ATM outage.

Referring now to FIG. 2, a device management method of comprises weighting performance metric data received from a plurality of managed devices with respect to a respective portion of temporal usage data associated with each of the managed devices to produce weighted performance data (Step 200). The weighted performance data is used to prioritize events associated with some of the plurality of managed devices (Step 202).

Referring now to FIGS. 3 to 5, a management portal GUI 300 displays a homepage 302. Typically, the homepage 302 is a webpage defined using standard languages such as html or XML. The homepage 302 comprises and active network map 304, a KPI dashboard 305, usage indicators 306, KPI tabs 308 a-g, and priorities tabs 310 a-c.

The active network map 304 comprises a graphical representation of a territory 312. A region 314 of the map 304 corresponding to, for example, a state, county, city or town, can be highlighted within the map 304. Typically, the region 314 is highlighted by hovering a cursor over the map 304 and clicking a button, either on a mouse or on the keyboard. Each region 314 has nodes 317 associated with either a single ATM or geographical grouping of ATMs. Such a geographical grouping may be based around a county, city, borough, or a town. Alternatively, nodes 317 may be based about a group of ATMs serviced by a particular maintenance operative.

A dialogue box 316 opens over the region 314. The dialogue box 316 contains a legend 318 that identifies the region 314 and icons 320 detailing KPIs of interest.

In some embodiments, it is envisaged that a user of the portal GUI 300 can drill down to a detailed map of the region 314 by use of a magnification bar 322. In an alternative embodiment, it is envisaged that drill down to detailed maps can be effected by, for example, multiple mouse clicks.

The usage indicators 306 give a graphical representation of total ATM usage metrics within the region 314.

The KPI dashboard 305 comprises graphical representations of KPIs, for example in the form of bar charts 324. The bar charts 324 comprise a first bar detailing the actual KPI metric 324 a, and a second bar 324 b detailing an acceptable threshold level. In at least one embodiment, the first bar 324 a changes color, for example from green to red, when a threshold limit is crossed. The first bar 324 a may also change color when a threshold limit is approached, typically from green to amber. It will be appreciated that the second bar 324 b may be omitted if preferred.

The KPI dashboard 305 is updated periodically in response to performance data supplied by the management unit 106. The performance data supplied by the management unit 106 may be unadulterated performance data as received from the managed ATMs 102 a-d, or it may be weighted performance data.

The KPI dashboard 305 can be updated at a frequency defined by the user of the portal 300, for example every thirty seconds, every five minutes etc.

As a user drills down geographically within the map 304 the KPI values detailed within the KPI dashboard 305 will change to reflect the region 314 being viewed within the map 304.

The KPI tabs 310 a-g allow a user to switch between pages of the portal 300 detailing differing KPIs, in a manner known to those skilled in the art of web browsers.

The priorities tabs 312 a-c allow a user to tab between windows within the homepage 302, in a manner known to those skilled in the are of web browsers. Typically, tabbing between windows is achieved by hovering a cursor over a tab 312 a-c and clicking a mouse button.

When tabbed, a first of the tabs 312 a causes a list 326 of the current top priority faults to be listed, fault priority having been determined as described hereinbefore. Typically, the list 326 shows the ATM type 328, the location of each ATM 330, the incident that has caused the outage 332, the number of unserved customers associated with the outage 334 and a further user definable field 336.

When tabbed, a second of the tabs 312 b causes a template to be invoked, into which a user can enter priorities settings. Non-limiting, examples of priority settings include threshold limits, whether performance data uploaded from the management device 106 is to be unadulterated or weighted, and which KPIs are to be considered in determining priorities.

When tabbed, a third of the tabs 312 c invokes a list of KPIs. Referring now to FIG. 4, an UC trend page 400 of the portal GUI 300 comprises a graphical trend window 402, comparison period tabs 403 a-d, an UC breakdown window 404, view tabs 405 a,b, user definable tabs 406 a-c, KPI tabs 408 a-g, and view period tabs 410.

The graphical trend window 402 displays a line graph 414 showing comparative figures of UC data 414 a, 414 b for a specified comparison period. The comparison period is defined by tabbing an appropriate comparison period tab 403 a-d. Typical comparison periods are weekly, monthly, quarterly or yearly. A dialogue box 415 opens when a cursor is hovered over the line graph 414. The dialogue box 415 displays the comparative number of UCs at the point in the two comparison periods corresponding to the cursors position projected on to the abscissa. The line graph 414 has three bands 416 a-c, the lowest band 416 a is corresponds to an acceptable level of UC transactions, the middle band 416 b corresponds to a level of UC transactions that causes concern and the upper level 416 c represents an unacceptable level of UC transactions.

In the present example, UC data shown being compared between a current twenty four hour period, divided into hour long slots and the same period one week ago.

The UC breakdown window 404 displays either a graphical representation 418, or a textual breakdown of the transaction types that the UC transactions are expected to comprise based upon temporal usage data. The view tabs 405 a,b are used to switch between the graphical or textual breakdowns. In the present embodiment the graphical breakdown of transaction types is in the form of a pie chart although it will be appreciated that any suitable form of graphical representation may be used, for example bar chart or line graph.

The user definable tabs 406 a-c can be used to display whatever information is required by the user. In the present example the worst offending ATM in terms of UC transactions are displayed along with their location, the incident that caused the downtime and the calculated number of lost, or unserved, customers that the ATM downtime corresponds to.

The KPI tabs 408 a-g allow a user to switch between pages of the portal 300 detailing differing KPIs, in a manner known to those skilled in the art of web browsers.

The view period tabs 410 allow a user to tab between viewing UC data for the prior time periods and also predicted UC data for the future. Such predicted UC data may be generated by modeling, the projection of historic date or a combination of the two.

Referring now to FIG. 5, a transaction volume trend page 500 of the portal GUI 300 comprises a graphical trend window 502, comparison period tabs 503 a-d, a transaction volume breakdown window 504, view tabs 505 a,b, user definable tabs 506 a-f, KPI tabs 508 a-g, and view period tabs 510.

The graphical trend window 502 displays a line graph 514 showing comparative figures of transaction volume data 514 a, 514 b for a specified comparison period. The comparison period is defined by tabbing an appropriate comparison period tab 503 a-d. Typical comparison periods are weekly, monthly, quarterly or yearly. A dialogue box 515 opens when a cursor is hovered over the line graph 514. The dialogue box 515 displays the comparative transaction volume at the point in the two comparison periods corresponding to the cursors position projected on to the abscissa.

The line graph 514 has three bands 516 a-c, the lowest band 516 a is corresponds to unacceptably low transaction volumes, the middle band 516 b corresponds to a transaction volume that causes concern and the upper level 516 c represents an acceptable transaction volume

In the present example, transaction volume shown are being compared over the current twenty four hour period, divided into hour long slots and the same period one week ago.

The breakdown window 504 displays either a graphical representation 518, or a textual breakdown of the transaction mix that the transaction volumes comprise. The view tabs 505 a,b are used to switch between the graphical or textual breakdowns. In the present embodiment the graphical breakdown of transaction volumes is in the form of a pie chart, although it will be appreciated that any suitable form of graphical representation may be used, for example bar chart or line graph.

The user definable tabs 506 a-f can be used to display whatever information is required by the user. In the present example they comprise “on-us vs not-on-us” transaction volumes 506 a, deposit type 506 b, transaction mix 506 c, “on premise vs off premise” transaction volumes 506 d, ATM supplier comparison 506 e and location 506 f.

Thus, these user definable tabs 506 a-f allow a financial institution to compare statistics relevant to their concerns based upon any one of the KPIs graphically. For example, tabbing of the ATM supplier comparison tab 506 e allows the financial institution to readily determine which of their ATM suppliers machines is more reliable, in terms of lost revenue, UC volumes or downtime dependent upon which statistic is configured to be displayed.

The KPI tabs 508 a-g allow a user to switch between pages of the portal 300 detailing differing KPIs, in a manner known to those skilled in the art of web browsers.

The view period tabs 510 a-f allow a user to tab between viewing transaction volume data for the prior time periods and also predicted transaction volume data for the future. Such predicted transaction volume data may be generated by modeling, the projection of historic date or a combination of the two.

The transaction volume page 500 is shown as an exemplar of a KPI page of the GUI portal 300. Differing KPI pages will have graphical displays commensurate with the information to be displayed in relation to the KPI selected.

It will be appreciated that each KPI page may have unique user defined statistical functions linked to their user definable tabs. However, there may be user defined statistical functions that are common across two or more KPI pages.

It is envisaged that each page, or pane within a page, can be selectively highlighted to be saved independently, for example as a PDF file or a JPEG file.

It will be further appreciated that although described with reference to an SNMP architecture the present invention may be implemented using any suitable communication architecture, for example web services or a proprietary messaging interface.

It will be appreciated that although described with reference to a distributed network of ATMs the present invention can be any suitable managed network of self-service terminals, for example medical record entry terminals or self-check in/out terminals.
